"""
|
|
|
|
This module manage top sets for terms frequency.
|
|
Every 'refresh_rate' update the weekly and monthly set
|
|
|
|
|
|
Requirements
|
|
------------
|
|
|
|
*Need running Redis instances. (Redis)
|
|
*Categories files of words in /files/ need to be created
|
|
*Need the ZMQ_PubSub_Tokenize_Q Module running to be able to work properly.
